SHEARS.

Application filed `Tune 9,

To all whom t may concern:

Be it known that I, EUGENE N. ARNOT, a citizen of the United States, residing in the city of San Francisco, county of San Francisco, and State of California, have invented new and useful Improvements in a Shears, of which the following is a specification.

The present invention relates to a tirerepairing tool and has reference more particularly to a tool of this class which ,inchicles in combination a cutting device, an abrasive surface,amoistener, and a spreader for applying an adhesive substance.

The primary obj ect of the invention is to provide a tool which will include all of the above-mentioned elements in a single structure, so to speak, thus offering an exceedingly handy and convenient device for repairing tires; for instance, in applying patches to the inner tubes of pneumatic tires.

As heretofore practiced, various equipments have been provided, some of which being sold with tire-repair outfits for en abling the motorist to repair punctures and the like on inner tubes without necessitating taking the tube to a repair shop.

This equipment is not ordinarily always available when most needed as it usually includes separate parts which become easily lost and misplaced. In repairing a tube, the surface around the puncture must be thoroughly cleaned, preferably with gasoline, roughened, or vice versa, and then receive a coating of the adhesive substance. The patch should then be cut to proper size, and applied over the puncture. In performing this operation an abrasive material is required, such as sandpaper, emery paper, or the like, and for applying the gasoline which is usually in the tank of the car, a device should be used for insertion into the tank.

Then again in spreading the adhesive substance, a relatively flat and narrow instrument should be used. All of these steps require a more or less variety of devices, and it is proposed by the present invention to provide a tool which will embody in a single structure the necessary equipment for carrying out the above steps.

The accompanying drawing illustrates the preferred manner of reducing the invention to practice. In said drawing Figure 1 is a perspective view ofone side'of the tool;

1920. Serial No. 387,691.

Fig. 2 is a perspective view of the opposite side of the tool; and Fig. 3 is a cross-section on the line 3-3, Fig. 1.

Referring now to the drawings in detail: The tool preferably comprises a relatively long narrow strip produced of metal or any other suitable material, one end of which being looped upon itself as at 5, and having a cover of felt or the like material 6 which is secured by the rivet 7. The body of the strip intermediate its ends may be bent to provide a raised portion 8 with a covering of an abrasive material 9 detachably secured so that it may be replaced through means of the small nuts and bolts 10. The opposite end of the strip may be more or less pointed to provide a spreader 11 for the adhesive substance. In order to incorporate the cutting device as a feature, an L-shaped strip 12 is pivoted as at 13 in order that it may act together with the edge of the strip to produce a cutting effect, as a pair of scissors, for cutting the patch to the desired size. rlhe free end of the strip 12 may be bent upwardly to provide a lug 14 for conveniently realizing the cutting effect, with a notched portion provided as at 15 adapte-d to engage the headed end 16 of one of the bolts which secures the abrasive material to the device and with the headed end 16 of the bolt acting as a stop.

From the above it will be seen that the tool offers all the elements in a single structure necessary to apply a patch, thus doing away with the necessity of using a number of independent devices and avoiding the possibility of such devices becoming lost or misplaced and not accessible for use when desired.

I claim:

A cutting tool of the character described comprising as a dominating member alongitudinal metal strip and as a subordinate member an L-shaped cutter pivoted to the metal strip and adapted to co-operate with the side edge thereof to produce a cutting effect, the cutting edge of the cutter adapted to overlie the flat surface of the metal strip with the other bend of the L abutting against the side of the strip so as to preserve the single strip character of the tool when in an inactive position.
